Abstract (en)

[origin: EP0805397A2] A network and CD-ROM caching product that runs under both Windows 3.X and Windows 95, is completely transparent to end-users, and works with a wide variety of file systems running under both Windows 3.X and Windows 95 is disclosed. The approach used to fulfill these requirements has been to utilise the services provided by a virtual device driver (VxD) supplied with Windows 95 known as the Installable File System Manager (IFSMGR). Windows 95 is designed so that all file system input/output (I/O) requests may be "hooked" to the IFSMGR VxD. The disclosed caching product is effectively "layered" between the IFSMGR VxD and the generic file system of Windows 95. The disclosed caching product has been designed so that it will run under both operating systems. This has been accomplished by rewriting portions of the Windows 95 IFSMGR VxD, enabling it to run under Windows 3.X. The rewritten version is based on the IFSMGR specification provided by Microsoft Corporation. <IMAGE>
